The cleats 20 serve to form a guide for the screen reel because the-flanged cog wheels 14 run in the loops formed by the cleats 20. The screen 22 is attached 23. on the frame 7 and 8.

The bars 26 shouldbe one-fourth one-half inches'wide. Provision is made for stripping; the lint rom the screen 22.

- Gear whe'el30 is driven. by the cog wheel 14 and wheel' 30 drives is mountedwithin' the screen 22 and supported this pipe is'perforated .wheel 31. A. pipe 32 is to discharge compressed air forblowing t e that the blasts dischar' edfrbm the perforations 34 will not be di used but driven to the rollers 28 and 29, strippingthe lint from the.

the bars 26, as illustrated in Fig. 5. Compressed air is supplied to the pipe 32 from any suitable supply source. Provision is made for sealinga portion of the space with in the screen as the screen approaches the compressed air pipe 32. A partition 36 is extended throughout the width of the screen and attached to the housings 10. The object is to cut off a portion of the space within the body of the screen so that a relatively small part of the screen will'be exposed to the action of the air, approximately one quarter, more or less of the'periphery of the screen being so exposed to the action of the air. The part of screen -so protected by the partition 36 extends from the compression roller 37 to the roller 28. The roller-37 presses the air out of the cotton or other material and forms a bat of the material and the roller .37 forms a seal together with the partition 36 and guard members 33 so that the suction through the main body of the screen will not tend to draw the lint or cotton or other material backward towards the roller 37. A supplemental compressed air pipe 38 is placed below the roller 29 to co-operate with the rollers 28 and 29 in stripping the material from the screen and to prevent the material 48 from being blown down below the roller 29. The blower pipe 38 will be particularly use-- ful in case of heavy material, to prevent the material from falling down. This pipe 38 1s perforated in the same manner as pipe 32 for escape of air which is forced through the I p1pe.

Suction is created on the inside of the screen by a pipe 39 which leads from the atmosphere or a line of pipe and the air and dust redrawn through the interior of the screen and out through the pipe 40 to the fan 41 which discharges the dust and dirt or. sandinto a dust collector or to the atmosphere.

The air suction through the body of the screen 22 will draw some of the material through the screen 22 within the main body of the screen and this material will be caught on the bars 26. In order to clean the material from the bars 26 and put such material back on the outside of the screen, aportion of the periphery of the screen 22 will be out off or separated from the main space within the screen by a partition 42 which extends the full width, the same as partition 36, of thescreen and is attached to the housings 10. A pipe 43 is run through this cut-oil space and a pipe 44 is connected to pipe 43 and extended up and projected through an opening into the interior of the housing 21 so that this material brbught up by" suction through the pipe 44 i will be again thrown on the outside of the v screen 22.

The rollers 28 and 29 form a hat, of the .cleaned fibre which descends on the chute 45 to be delivered to a press (not shown). The lint or a material to e condensed comes from the gin stands (notshown) through the pipe 39 and is thrown'on the revolving screen 22. The dust is drawn out through the screen and discharged through the fan 41 and out through the pipe 46. The lint is condensed on the exterior of the screen 22 and stripped from the screen by blasts from pipe 34 and blown to the rollers .28 and 29 in the form of a bat and descends by way of the chute 45 to the press.

Various changes in the sizes, proportions,

which is passing the sealed portion bounded by the members 36 and 33. The sealed portion of the space within the sc'reenwhich is about the suction pipe 43 is provided with members 42 and 46 which serve to seal thesuction from that portion of the screen which is passing the member 46. The pipe 43 has a longitudinal slot 48 so that the material which is lodged on the bars 26 will be drawn into the pipe 43 as each bar 26 passes the slot This application is; filed 'as'a substitute for my application filed Oct. 31, '1925, Ser. No. 65,960, allowed March 5, 1928.

\Vhat I claim is 1. A condenser and cleaner comprising a revolving screen and a housing therefor, circular tracks rigid with said screen, a pair of shafts and trunnions on said shafts for sup-' porting said screen, gear wheels rigid with.

said tracks, a pinion on one of shafts for driving said screen, means for delivering material to said screen to be cleaned and condensed, and means for stripping the condensed material from said screen.

2. A condenser and cleaner comprising a reel consisting of two circularv frame members and bars connected to said frame mem bers for spacing and holding said members through said screen and delivering material thereto, and means for stripping material from said screen and forming a bat thereof.

'terial on said screen and means for 3. A condenser and cleaner comprising a revolving screen and a housing therefor, C11- cular tracks rigid with sa1d screen, a pair of shafts and trunnions on said shafts for supporting said supporting said screen by tracks, means attached to said"housing for guiding said screen preventing displacement thereof, pinions on one of said shafts for driving said screen,'means for creating suction through said screen and delivering material thereto, and means for condensing mastripping material therefrom and forming a bat there- 4.- A condenser and cleaner comprising a revolving screen and means for creating suction therethrough and delivering material thereto, means for condensing material thereon, rollers for stripping material therefrom and forming abat thereof, and a blast pipe below said rollers co-operating therewith,

for forcing material between saidrollersl 5. A condenser and cleaner having a revolving screen consisting of two circular frame members having lateral flanges projecting inwardly and provided with radial slots, bars for spacing said frame members secured in said slots, a wire mesh supported on said bars and covering said flanges, said flanges having circular cavities, wooden plugs in said cavities, staples driven through said screen into said wooden plugs for securing the screen to sa1d flanges, means for creating suction through said screen and for delivering material thereto, and means associated with said screen for condensing the cleaned material and forming bats thereof.

6. A condenser and cleaner having a revolving screen and means for creating suction therethrough and delivering material thereto, means for condensing material on said,

screen means for stripping material therefrom and forming bats, means for removing material from the interior of said screen consisting of a suction pipe provided with a longitudinal slot adjacent to the interior of said screen and means for sealing a space about said suction pipe from said screen, ex cept along said guarding means adjacent to said slot, and an extension of said suction Eipe extended upwardly and within the screen ousing for delivering the material to the outside of said screen.

In testimony whereof, I set my 23rd day of November, 1929. 1
